Precautions for processing tungsten copper rods

Tungsten copper rod is a two-phase structure pseudo-alloy mainly composed of tungsten and copper elements. It is a metal matrix composite material. After the composite materials are mixed, no chemical reaction occurs, and each maintains the original physical and mechanical properties. This material is prepared by a specific process method of powder metallurgy. Tungsten forms a skeleton in the alloy, and copper penetrates into the gap of the tungsten skeleton, which combines the advantages of high melting point and high temperature resistance of tungsten itself. The notch sensitivity improves the plasticity of the alloy.

Of course, when processing the tungsten copper rod, the corresponding precautions need to be known. When machining tungsten-copper alloys to make sharp corners and thin walls, defects may occur due to impact or excessive machining load force. When tungsten-copper-silver-tungsten alloy products are drilled through holes, please pay attention to feeding when the through holes are about to be drilled. Load force, avoid machining defects, tungsten copper alloy is non-magnetic, please confirm that the product is firmly fixed before operation.
In addition, the discharge and wire cutting speed of electric discharge machining and wire cutting tungsten copper rods are relatively slow, which is a normal phenomenon. For alloys composed of tungsten and copper, the copper content of common alloys is 10%-50%, and the alloys are made by powder metallurgy method. It has good electrical conductivity, thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000 degrees Celsius, the copper in the alloy is liquefied and evaporated, absorbing a large amount of heat and reducing the temperature of the surface of the material. Therefore, this type of material is also called metal sweating material.
